Answer:d
Step-by-step explanation: because when you make an error and don’t know you write it down plus doctors have to write down everything they do to a patient in their chart by law
2/3 girls that's mean there is 1/3 boys.
If there are 18 girls that mean half this number is the boys which is 9.
Therefore, total number is 27.
Answer:

Step-by-step explanation:
step 1
Find the slope of line L
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal
In this problem we have

Isolate the variable y

The slope of the given line is

so
The slope of the Line L is

step 2
Find the x-intercept of the line

The x-intercept is the value of x when the value of y is equal to zero
so
For y=0

The x-intercept is the point (5/2,0)
step 3
Find the equation of the line L
Find the equation of the line in point slope form

we have

substitute


Convert to standard form
AX +By+C
where
A is a positive integer
B and C are integers
Multiply both sides by 4
